Abstract

The Q-switched laser performance of a diode-pumped Nd:YAlO3 laser, discretely tunable between 1.064 and 1.099 μm, is reported. Intracavity frequency doubling yielded outputs of 253 and 144 mW at 532 and 550 nm, and with external conversion to the fourth harmonic, 22.5 and 6.7 mW were obtained at 266 and 275 nm. Polarized absorption curves for the diode pump bands from 780 to 830 nm and spectroscopic measurements of the polarized emission cross sections for the 4F3/2 → 4I11/2 band are presented.
